Shadowrun Returns

Bug in late game (SPOILERS), my character takes like 10 seconds to perform an attack

Hi, just reported the bug to the developer but I'd like to know if someone had the same problem and there's something that can be done to solve it.

In Beneath the Brotherhood chapter, after taking the elevator to find Jessica Watts, my character starts acting slowly, like taking around five seconds to perform an attack. When I click any action (shoot, magic, grenade...) he starts the animation, like two seconds later finishes it, and a few seconds later the enemy receives the attack. My companion characters act without problem. Tried to reset, the mission, even let myself to get killed and the problem persists.

What can I do? I tried to finish the chapter like that but I got killed and lost so much time waiting that I'd like to solve it before continuing.

I just stoped playing it because of it. My drones attack like normal and so does my party member but its just me. I don't think a medic drone an air drone and a girl with a shotgun can take out all of the guys in late game. I barley survived the fight with Holmes and I had a mage, shaman, decker, 2 attack drones and me with high level rifle skills
